Communication systems at millimeter waves for ITS applications

This paper refers to the work carried out by the author in the framework of the Italian project TELCO, which aims at defining a communication system for cooperative driving applications. Inter-vehicle and beacon-to-vehicle communications at 63.5 GHz in highway environments are investigated. The purpose of the paper is network performance evaluation by considering a multi-hop reservation Aloha protocol, proper transmission techniques and a suitable propagation model. The performance is assessed both by means of a simulation tool and analytical modeling, in terms of packet success probability and deadline failure probability; the main protocol parameters, such as the total bit rate and the number of slots per frame, are defined
